Applicatioufiled October 1, 1901. Serial No. 77,201. (No model) from the process is prevented and also the noise is deadened and muffled, while at the To all whom, it may concern:

Be it known that I, HANS O. WESTMARK, a citizen of the United States, residing at Aurora, in the county of Kane and State of Illinois, have invented certain new and useful Improvements in Boiler-Flue Rattlers, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

The purpose of this invention is to provide a machine for rattling'boiler-flues for the pn rpose of detaching scale and other incrustations which result from their use in boilers supplied with water containing large quantities of lime and other minerals, from which The invention consists in means for tumbling the flues in a chamber adapted, preferably, to contain water sufficient to cover the flues in the process, so that dust arising same time the incrustation is partly dissolved and rendered more easy of detachment by the action of the water.

It consists also in means for tumbling the flues in a receptacle without rotating the receptacle and means for delivering-them thereinto conveniently from a loaded car and for delivering them therefrom conveniently and substantially without handling onto a car by which they maybe removed.

It consists, further, in details ofconstruction which are set out in the claims.

In the drawings, Figure 1 is a transverse vertical section of my improved flue-rattler and its foundation-supports. Fig. 2 is an end elevation of the same, the track and approaches thereto and the pit and foundationdled. Fig. 6 is a detail elevation of the de-' fiector-terminal and detent-dogs. detail plan of drum connections.

My improved rattler comprises a cradle consisting of bars A, suitably supported in parallel position, defining the outline of a semi- Fig. 7is a Fig. 5 is cylindrical receptacle in Which the fines to be cleaned may lie and be rolled transversely. The means of thus operating the tines consists of a shaft B, extending longitudinally above the cradle at the center of the semicylindrical receptacle defined by the cradlebars and having any desired number ofsweeparms 0 secured to it and revolved by it,

sweeping transversely through the semicylindrical cradle, so as to carry the fines lying therein up at one side of the shaft and permit them to fall over at the other side back into the cradle. The cradles outlines are continued, necessarily,'at one side up above the horizontal diameter to retain the fines on the sweep-arms as they rise. This is done by the use of the curved bars D, which for another purpose (hereinafter explained) are secured to a longitudinal shaft E, about whoseaxis they may be swung slightly, but which holds them normally in position, so that their inner concave faces correspond to the cylindrical outline of the cradle and to the path of movement of the sweep-arms. These bars D extend upon the side of the cradle at which the sweep-armsTise, the bars keeping the lines on the sweep-arms until they are lifted so high that they tend to roll down inward and fall into the cradle at the opposite side of the shaft from that on which they were lifted by the sweep-arms. Preferably the sweep-arms are two in number, extending in diametrically opposite directions and being integral with each other, as shown in the drawings, so that as the tines are carried upward at one side past the horizontal diameter far enough so that they tend to roll down on the arms they may be guidedby the arms and kept thereon in their whole advancing movement, and thus practically kept under control, rolling upon each other as they roll upon the sweep-arms and never falling as a mass bodily without support, as they might other- Wise be liable to do, with danger of becoming crossed and tangled in falling. I do not limit myself, however, to two sweep-arms; bnt any desired number may be employed, the sweeps being arranged, preferably, at equal intervals about the shaft. The sweep-arms, however, preferably have webs or flanges b 1), upon which the flues rest and roll, said flanges being widened at the center, so as to direct the fines past the shaft. Each pair of sweep-arms is preferably made of two parts cast from the same pattern and symmetrical about a plane transverse to the axis of the shaft, so that they may be applied to each other in reverse position and bolted together upon the shaft. The sweep-arms thus produced have the edge outline of the pipe-supporting webs, at one side curved concave forward in the direction of the pipe-encountering movement of the arms, the other edge being approximately straight and radial. This form tends to cause the fines to start rolling down past the shaft as soon as they pass above the level of the same and to prevent those nearthe outer end from being thrown by the sweep-arms or being delayed in starting down so long as to be liable to fall abruptly when they do start. The cradle formed of the bars A is within a chamber adapted to contain water,such chamber being semicylindrical, widened at the top by flaring lateral extensions of the curved wall. The preferred construction is that shown in the drawings, in which the watercontaining chamber is made in sections F F F, of which the webfconstitutes the wall of the chamber and flanges ff means of securing successive sections together, so as to make a chamber of any desired length, the ends being formed by plates G G, bolted or riveted to the outer flanges of the outermost sections. These cast sections constituting the chamber may be formed with bosses F F, &:c. projecting radially inward from their web f at intervals over the semicylindrical portion to support the cradle-bars A A A, which are bolted thereto, as illustrated. Inclined ap proaches to the semicylindrical portions of the cradle are formed at their opposite sides by the inclined extensions A and A of the cradle-bars A, the former being at the entrance side and adapted to guide the fines down into the cradle and the latter being at the delivery side, forming part of the guideway by which they are delivered from the cradle and lying flat upon the flaring lateral extensions F and F of and corresponding to the sections F F F of the main cylindrical portions of said chamber.

K and L are brackets mounted on the foundation-walls M for supporting the extensions F and F respectively.

T T are I-beams extending longitudinally above the cradle, resting on the masonry walls at the opposite ends, being located high enough to be beyond the sweep of the sweeparms. On these I-beams are mounted the rails U U of a track on which cars may run to a position directly above the cradle for the purpose of delivering the flnes into the latter, the delivery being made by rolling the fines off sidewise from the cars, so that they may fall onto the inclined end portions A A of the cradle-bars.

B B, &c., are brackets which may be pro vided bolted to the outer side of the rails B on the receiving edge of the cradle,these brackets having webs B whose edges, standing parallel with the upper faces of the cradle-bars at a distance inward therefrom sufficient to afford passage-way for the largest-sized fines which will be handled in the cradle, define a channel or throat a, through which the flues roll into the cradle when they fall laterally from the car. Preferably the space between the track-rails and outside the same to the edge of the brackets D at the receiving side and to the path of the fines between the arms D and O at the delivery side is covered over by a fioor W. The bracket W may be mounted on the flooring at the outside of the track at the receiving side, having inclined upper edges to guide the fines as the fall from the car into the throat or channel a, and at the opposite side of the mouth of said channel there may be mounted upon the masonry inclined guide-brackets W W to guide the fines from the outer side back into the inletchannel. ThebarsD,whichconstitutetheupper portion of the cradle at the delivery side, but above the point of delivery, are formed as terminals of arms D, formed with cylindrical bosses D apertured to receive the square shaft E, journaled in the head-plates G G. The shaft may be rocked to carry the bars D D from the position at which their inner faces correspond with and constitute a continuation of the cylindrical outline of the cradle to position shown in full line in Fig. 1, at which the lower pilot-points d of said barsD protrude inward into the space of the cradle and overhang the path of the outermost row or layer of fines carried upward by the sweep-arms. Inthis position the lower edge of the arm D is parallel with the outwardly-deflected portions A of the cradle-bars A, so that there is formed between said deflected cradle-bars and said arms D an inclined passage-Way leading upward and outward from the cradlespace. The arms D extend past the bosses D in a curved direction, and on the upper inclined face of the flaring walls F which constitute the continuation of the water-chamber at the delivery side, there are mounted and made rigid upstanding guide bars 0, which are curved to correspond with the curvature of the arms D and paralleltherewith at the position occupied by said arms when the bars D are set protruding their lower or pilot-points d into the cradle-space to engage and deflect the outermost row of fines. There is thus formed a guide-channel for the fines, in which they are conducted upward when they are pressed from behind by the sweeparms, which occurs when the direction of rotation of the shaft is reversed, for which provision is made in the driving mechanism. To the upper ends of the arms D and upstanding bars 0 0 there are secured extensions P and Q, respectively, curved so as to be parallel and constitute a continuation of the gnideways for the fines, by which they are conducted upward and guided over laterally,

so as tobe delivered from the upper end of such guideways downward by gravity onto cars prepared to receive them standing on the tracks above the cradle. of the arms D and bars 0 are provided with The upper ends terminals D and O at the lower ends of the curvedguides P and Q, having square sockets, adapting them to be lodged on said square terminals. These terminals and sockets are of the same dimensions, .so that the parts P and Q are interchangeable, and being interchanged or transposed may be set in reversed position, so as to curve outward instead of outward onto cars standingon outside track. In order to insurethe separation of the outer layer or row of fines from the remainder asthe sweeps carry them up at the delivery sideand to prevent the lower point of the deflector D from colliding with the flues of the next inner row instead of entering between themand separating them,'I provide on the back side of the sweep-arm lugs or partingfingers b b at such distance back from the end as to leave room for one fine between them and the cradle-barsA, the presence of these fingers projecting substantially the diameter of the fines, so that the fines of the second row or layer are prevented from lodging deeply between the fines of the next inner layer, and are thus held imposition such that the pilot-point d of the deflector D readily enters between the outer and next inner row or layer of lines. In order prevent the fines from being able to returninto the cradle after having been forced out into the discharge passage, I provide at the entrance of said passage, pivoted to the deflectors D, dogs S S, &c., adapted by their form to hang normally in position to close the passage, as seen in Fig. 1,

and stopped in that position against movement inward in respect tdthe cradle by the shoulder d of the deflector near the pivot of thedog, but free to swing in the other direction to allow thefiuesto pass them as they are forced outward. Any flue which is carried beyond the dog isprevented from returning, andthns in each sweep ofthe sweep-arm after the deflector is set so as to open the discharge- .5

passage all the fines in the outermostrow or layer will be forced into the passage,and this process will be continued each time the arm passes the deflector until the fines are all contained in a single row and'are all delivered past the dog. To complete the delivery out of. the dischargechannel, any convenient means operated by hand may be employed.

In order to provide for delivering the fines to the rattler at the sameside from which they are discharged therefrom whenever this may be more convenient, the guides P being I removed and the guides Q being left in place on the upper ends ofthe guide-bars O, in-

clinedbars X X being substituted in the sockets. at the sides of thecars for theretaining-stakes which are employed to keep the load on thecars, the flues may be allowed to move down such inclined bars, and are thereby directed into the guide-passage between the bars D and O and follow the same down into the cradle. In orderto load the rattler at this side, it is necessary to provide for holding the dogs F F out of the channel, and for this purpose all the dogs are preferably mounted on a single shaft, journaled in the deflectors B, the shaft having a lever-arm near one end, which can be reached from above to rock the shaftand carry the dogs out of operating position.

Inorder that fines of different diameters within limits may be properly discharged upward through the passage-way formedby the bars D and 0 Without danger of becoming choked or jammed therein when they are of considerably less diameter than the full width of the passage-way, I provide the arms D and P with adjustable face-plates D and P, respectively. The face-plate D is held out from the arm D by springs d lodged in pockets provided for them in the arms D, and said plate is drawn back to any degree necessaryby screws D D retained by nuts d at the back side of the arm D, by which any desired adjustment is made. The guides P and Q may be similarly provided with faceplates 19 and q, held to said guides, respectively, by yielding strips 19 and g, which tend to hold them in against the face of the guides by screws 19 and g1 being set through the guides to force the plates off therefrom to any desired degree to narrow the passage. for the fines. w

The means for rotating the shaft B is seen in Figs. 2 and 5, comprising two sprocketwheels B B on the shaft B outside the cradle and its chamber and a counter-shaft B having loose sprocket-pinions B B which has feathered on it a clutch-collar B4 between the pinions, said collar being adapted by familiar means (not illustrated). to be shifted. into engagement with either of the pinions at will. The chain B from one of the pinions passes directly about one of the sprocket-wheels B The chain 13?, passing around the other wheel B and about the idle sprocket-wheels l3 and B 9, is diverted about the other pinion B which engages theback side of the chain to communicate motion through the chain,which thus derives motion in opposite direction from. chain B The counter-shaft is driven by chain 13, passing about the wheelB on said counter-shaft,deriving power from any source.
